A spreader beam and related method provide a simplified repair or rebuilding capability for wear parts of the spreader beam. The disclosed spreader beam includes removable sheave nests containing sheaves, which are the wear parts in a spreader beam. The disclosed spreader beam saves time and costs since an entire spreader beam need not be transported to a repair shop, rather only the removable sheave nests, or only the sheaves. In one embodiment, sheaves and sheave nests may be removed and replaced without the need for unwinding supporting cables.
